Is it normal for a clinic to require money upfront when scheduling online?

Hi everyone!

I am not new to plastic surgery but I am new to getting it done overseas. I have been in contact with a clinic in Korea and I found out last night that I will need to pay a fee in order to book my appointment. I am planning on going in May to get neck done (neck lift) as I have had a bit more sagging than I would like going on. The cost was just too high to get it done locally so this is what led me to look in to options in other countries.

I am just not sure if this is normal. They did say the money I pay will be part of the total cost so it will be deducted when I arrive to pay the rest. Is it normal for a clinic to require money upfront when scheduling online?
